For the life of me I can't get ScummVM to properly play the DOS version from the hybrid CD-rom.

When I go to add a game from the folder, it detects both the DOS and Windows versions. However, when I start the DOS version it attempts to play HDLOGO.AVI, which is the windows version logo. The DOS version of this is in the SEQ folder. Then if you choose to play the games opening, it attempts to play TOON.AVI, the windows intro movie. Again, the DOS version of this is in the SEQ folder.

This are minor issues that show it's not a true DOS version. The real issue comes into play once you start playing and talk to someone, such as the Guards at the castle. At this point it will show a portrait of Alexander's face. The Windows CD version had high-res portriats, however the DOS CD version used the original low res portraits. ScummVM is attempting to use the highres. This suggests to me it's not even using the DOS code, and is instead just playing the windows version regardless.

Technically, the DOS version doesn't even require the ACTORS folder, which is where the high res portraits reside. Yet if this folder is missing, the DOS version throws up a console error at this point in the game and you can't continue.

Unless I'm missing something, ScummVM doesn't have actual support for the DOS CD version of the game.

There's a flag in the engine options tab to use the hi-res art or not. This is so you can play the DOS version (with full colour DOS cursors) while using the hi-res portraits which wasn't possible previously without a Win3.x installation in DOSBox or an older computer. It's a feature. But one that you can turn off. There was also an option to enable/disable the grayscaled windows cursors.

As long as its set once in the game's options it should be permanent. There's a scummvm.ini (or is it .cfg?) somewhere on your system, whether in the ScummVM folder or in %appdata% or My Documents or whatever, with every game entry's settings stored inside it which is read by ScummVM at launch.

That's interesting though that the checkbox for the hi res portraits also controls whether the game uses SEQ or AVI videos. If that's the case, what's the point in having two entries (Windows/DOS)? Is there anything else that designates whether the game is the Windows or DOS versions?
